We are currently
developing an ice core melting and analysis laboratory at Dartmouth
College, including an ice core melting system with discrete sampling (see our publication describing this system here),
an ion chromatograph for major ion analysis, and freezer facilities for
sample storage. The lab should be fully operational by January, 2011. I am
also working with Bob Hawley and Zoe Courville to enhance the ice core
processing facilities at CRREL, located just down the road from the
Hanover campus, to provide clean ice sampling and ice core cutting
capabilities. Through collaborations with Prof. Feng
and Anthony
Faiia in the Dartmouth
Stable Isotope Lab,
we also have the ability to analyze d18O
and dD
ratios in ice core
samples.

hand auger. The ice core lab has access to a Kovacs Mark III hand auger
(similar to the PICO pictured above) recently purchased by Prof. Hawley. |

An ice core slab melting into the custom-made ice core melt head, which
collects pristine meltwater from the center of the ice core for
chemical analyses.

The ice core meltwater is pumped from the melt head to be collected in
pre-cleaned bottles by three fraction collectors under HEPA clean
benches.
